Federal health officials are under fire for their unclear public warnings after one death and nearly 200 cases of vaping-related lung illnesses, which some say are related to the far riskier practice of vaping marijuana oil rather than nicotine.
Some state health department and news reports suggest many of the cases of lung problems involve tetrahydrocannabinol, known as THC, the chemical in marijuana that causes psychological effects.
Boston University public health professor Michael Siegel said the Centers for Disease Control and Prevention is being “unnecessarily vague” about describing the injuries as simply vaping-related when many people might have been injured by vaping THC oil.
